Lynham added that he wanted more transparency on dust monitoring, outlining ways this can be achieved.

He said “firm action” was taken on a mine that went over regulated dust limits in March, aiming to bring it back to set limits.

Six cases of CWP have been confirmed in Queensland.

In January Lynham announced a five-point action plan to help determine CWP in miners, which included a review into current screening systems for workers, and improving the collation of information to ensure potential cases are not missed.

Queensland University of Technology (QUT) robotics researchers say they have developed new technology to equip underground mining vehicles to navigate autonomously through dust, camera blur and bad lighting.
